<div class="DESCRIPTION">
<p>
</p>
<p>
<b>Tangible User Interfaces</b> (TUIs) are bridges between the digital and physical worlds that we inhabit, making the former accessible and manipulable, by using the real world as a display and as medium for manipulation.
</p>
<p>
One such instance is the <b>Tabletop tangible interface</b>, or Interactive surface, so called because a horizontal surface is used by one or more people to interact with a digital model.
</p>
<p>
This is a systematic exploration of possible designs for a <b>low-cost</b> and <b>portable</b> Tabletop tangible interface.

</p>
<blockquote>
<p>
</p>
<p>
Right now there have been created 12 patches (tangible objects) that implement these modular synthesizer modules:
</p>
<ul class="org-ul">
<li>Amplifier with lfo input</li>
<li>A multi-effect with chorus, phaser and mixed function.</li>
<li>A multi-filter with low-pass, high-pass and band-pass function, plus a cut-off frequency generated envelope (GE) with lfo input and a "midi keyboard plug-in that sets the cut-off frequency equal the midi-pitch and a volume GE. This way it could function like a silly Subtractive-synthesizer if you connect it with noisy input..</li>
<li>Delay effect</li>
<li>Sample player with 8 samples</li>
<li>A sine-wave oscillator that also functions as carrier by connection to it a frequency modulator, and also volume sliders for the sine harmonics of the frequency and a GE working when midi keyboard is on.</li>
<li>Noise oscillator</li>
<li>Microphone input with a midi-keyboard vocoder plug in (fixed chords).</li>
<li>A multi-oscillator with sine, saw, square and triangle oscillators, plus midi-keyboard in.</li>
<li>lfo (sine, saw, square and triangle oscillators).</li>
<li>modulator that takes sine-oscillator patch's frequency and user sets the modulation index and the frequency ratio.</li>
<li>Master volume controller.</li>
</ul>
</blockquote></li>
<li>reacTable mentions that they have abstractions (instruments) built on the simpler puredata objects</li>

</p>
<blockquote>
<p>
"In analog electronic music, a synthesizer is built from several modules, or parts:
</p>
<ul class="org-ul">
<li>The Oscillators, which generate the tones.</li>
<li>The LFO (Low Frequency Oscillator), which usually modulates either the frequency or gain of the Oscillator(s), or the frequency of the Filter.</li>
<li>The Filter, which emphasizes and/or removes certain frequencies.</li>
<li>The Envelope Generator, which controls changes in frequency or gain over the duration of the note.</li>
<li>The Amplifier, which controls the gain of the synthesizer.</li>

[The trouble is, Pure Data community is using "Dynamic Patching" to mean dynamically creating new objects; whereas I mean it in the reacTable sense – dynamically connecting objects based on their proximity]
